Abstract
This article introduces CO2 and H2 generate dimethyl ether, new technologies for the synthesis of oxalic ester by using CO under the normal atmosphere and gas phase, studies on the conversion of methanol to propylene over HZSM-5, the investigation of liquid phase synthesis of methyl formate from CO, the economic introduction for methanol to generate lower carbon, and a comparison of production processes of methyl formate with the carbonylation of methanol and its market analysis. The the use of CO2, CO, and methanol is explained in detail. This is an economic and social benefit for chemical plants and the country by using CO2, CO, and methanol.
